5 Important Things to Consider When You
Compare Home Water Purifiers
compare home water purifiers, there are five very important
things to look for. That is if you really want safe home water
that is, also, affordable.
The popularity of home purification has meant that better more
effective systems have been designed, but there are pretenders
among them that are not actually purifiers, at all. Here's how
to spot them.
Every company should provide
product performance data, which includes certification by an
independent laboratory, such as Underwriter's. When you compare
home water purifiers, you should only consider the products
that provide this data, either on the company website or the
outside of the box. The percentage of reduction, as well as the
contaminant, should be listed.
For clean and safe home water,
one of the things that you want to look at is lead reduction.
Lead is a hazardous heavy metal that is naturally occurring in
many sources, but that doesn't mean that it is safe. There is
no safe level for lead consumption. The best products include
an ion exchange step for removal. Products that rely on reverse
osmosis only reduce lead to the "federal action level"; not
When you compare home water
purifiers, you will see that almost all of them (except the
pitchers) remove cysts. Many people think that reverse osmosis
is the only reliable method for cyst removal. Sub-micron
filtration is just as good and costs a lot less. If you want
safe home water that is also affordable, look for sub-micron
If you look for THM reduction,
you will really reduce your choices. The department store
models do not reduce THMs. So, they "really" do not provide
safe home water.
There is a "cancer epidemic"
in industrialized societies and researchers have been trying to
find out why this is true. Turns out, THMs in the water are a
big part of the problem. There are thousands of cancer-causing
chemicals in publicly treated supplies. Many of them are in the
environment and the foods that we eat. Sometimes, they are
unavoidable, but, if you only compare home water purifiers that
reduce THMs by 99% or better, then you can at least protect
yourself from that carcinogen.
What's the real cost of safe
home water? If you only consider the cost of purchasing, then
you would buy a PUR or Brita filter. PUR does make a model that
provides effective THM reduction, but it is not the model that
you commonly find in department stores. Most people don't yet
know about THMs. They think chlorine is the big problem. For
people who do know, better models are available, but the price
is higher and they have to be ordered on-line.
But, even if you buy the PUR
or Brita model that does reduce THMs, your cost of use will be
higher. What I mean is that those brands are only good for
about 100 gallons, requiring replacement every month of two at
a cost of $20 each. The better brands are good for 500 gallons,
five times as long, with a cost of only $40. In other words,
the cost per year is higher for the inexpensive brands. So,
when you compare home water purifiers, look for one that's good
for 500 gallons. It just makes good "cents".
